Application filed February 26, 1915. Serial No. 10,706;

'5 of Pennsylvania, have invented new anduseful Improvements in Smoke-Consuming Furnaces, of which the following 1s a specification. I a

This invention relates to furnaces, and

boiler, to a supplemental and auxiliaryheater, which is separate anddistinct' from the main fire-box, and from thencefto the main fire-box.

It is a further object of the invention to provide a supplemental and auxiliary firechamber immediately below the boiler of the engine to which the smoke and products of combustion are passed and where .they are consumed or burned, the heat generated thereby beingutilized to directly heat j the water in the boiler and the water in a water jacket about the supplemental and auxiliary fire chamber, the water jacket being in communication with the water in the boiler. j

The above and other objects of this invention'will be more fully brought out in the following detail disclosure of one embodiment'of this invention, the same being illustrated in the accompanying drawings.

in which,

locomotive disclosing the present embodiment of my invention. Fig. 2 is an enlarged detail section taken on'line 2-2 of Fig. 1 horizontally through the forward I end. of the supplemental and auxiliary combustion chamber. Fig. 3 is a transverse section taken on! line 3-3 of Fig. 1. Fig. 4 is avertical fragmentary section taken-on J1me 4 4 of Fig. 1.

.fire-tube: boiler 10, acombustion' chamber 11 at the rear end of the boiler, a grate 12 hand ash. pits 13 and 14, theash pits being In the drawings is disclosed a locomotive more particularly to an improved spark ar-- Figure 1 s a longitudinal sectionof a separated by a vertical transverse wall 15 for a purpose hereinafter disclosed.

At the forward end of the boiler 10 is a smoke box having a diaphra or partition wall 16 inclined downwartfil y and forwardly, and passing to within a short distance of the bottom of the smoke box,

whereby the latter is divided into chambers 17 and 18. The opening'beneaththe diaphragm 16, through which communication between chambers 17' and18 is established, is adapted to be closed by a damper 19 hingedly mounted upon the lower end of the diaphragm 16, the damper being connected to a rod 20 which "may extend to the cab of a locomotive or to any other convenient place where the attendant may operate the same to open or close the damper. "When it is desired to start the fire on the grate 12,

the damper 19 is raised into the dotted osition shown in Fig. 1, so that the cham er 1? communicates with chamber 18 and a draft is obtained through the fire-tube chambers 17 and 18 and the stack 21. The

damper 19 is maintained in open position until the fire is well-started and sufiicient steam pressure is obtained for operatingthe hereinafter described fan, after which the damper must be closed.

Immediately beneath the boiler and extending substantially throughout its length is a combustion chamber 22 which, as shown in Fig. 4:, is substantially rectangular in cross-section. The wall of the boiler 10 serves as the covering wall of the chamber" 22, and the side walls and bottom of the fire chamber are provided with a water jacket 23. Any suitable means may be provided .whereby the water in the water jacket 23 'is adapted. to communicate with the water in the boiler, in the present instance, ports or openings v24; are disclosed as passing The oil when led into the chamber 22, va-" porizes and with the steam, to-;ether with the air admitted through the diaphragm or is notinjured by the heat-generated in the main fire-box, and that it cannot be damdamper 26 forms an intense heat which willburn or consume the products of combustion led into the chamber, Abaflie plate 27 is provided immediately in front of the opening through which the burning oil and steampass for the'purpose of spreading the flame from the burner and causing the the combustion chamber and the boiler, so as to more readily heat the Water within the same. It will be noted that by providing such a fire chamber in the location above set forth the heat generated by'the burning of the smoke is used to heat the water within the boiler 10 and the water jacket 23 whereterially increased, while, at the same time,

no part of "the calorific" properties of the fuel, which is used to heat the boiler, is lost.

It Will be further noted that by providing the oil burner 25 in a chamber, distinct and separate from the main fire-box, the burner aged by the fireman when he stokes the fire on the fire-grate 12.

The smoke and cinders are conducted from the chamber 17 of the smoke box tothecombustion chamber 22 by means of a passage or pipe 28 which is provided onthe outside of the boiler 10. 'At the topof the boiler and in the passage 28 is provided a" fan 29, the suction side of which is connected with the chamber 17 as shown by the arrow 31, and the outlet or discharge side of which leads to the combustion chamber 22.

The productS of combustion from the com-' bustion chamber 22 pass rearwardly through After the fire is well started and the damper 19 is lowered so as to prevent communication'between chambers 17 and 18, as above set forth, the fan 29 is operated and a draft is produced thereby through the ash pit13',

the portion of grate 12 over pit 13, com

' bustion chamber 11, the fire tubes in the boiler 10, and the products of combustion pass'fromthe smoke-box chamber 17 through the passage 28 into the fire cham* ber 22 where the productsof combustion are burned and the heat utilized toheat the water in the boiler 10 and the water in the jacket 23, and fro'm'the chamber 22 the gases are further forced through the passage '30 into ash-pit l tandthrough the grate 12 where should any-unburned portions-of the products of combustion be present they'will burn with the fuel upon the grate 12.

While the present embodiment of this in ventlon discloses my improved spark ar rester and smoke consumer in combination disclosure being for the purposes of illustra- I v 1 tion only. It 'is obvious: that the structure same to come into contact with the walls of is susceptible of further modification in within the scope of the claims without departing from the What I claim is,-
